Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed May 12, 1819. Serial No. 296,522.

To all 107mm it may concern:

Be it known that 1, Eowano M. ERIOKSON, a citizen of the United States,and a resident oi Ray, in the county of Pmal and State of Arizona, haveinvented certain new and useful Improvements in Miners Lamps, of whichthe following is a specification,

My i vention is an improvement in miners lamps, and has for its objectto provide a simple, strong and etlicient lamp wherem all the parts aremade detachable tor quick and easy cleaning. I

In the drawings:

Figure 1 is a vertical section of the improved lamp;

Fig. 2 is a side view;

Fig. 3 is a detail perspective view showing the hook and itsconnections;-

Fig. 4 is a partial top plan view of the bail.

In the present embodiment of the invention the improved lamp consists ofa body composed of a lower section 1 and an upper section 2, the saidsections having threaded. engagement as shown. Thus a closed containeris provided, the top 3 of the upper section being, however, removable asshown, and this top has filling nipple normally closed by a screwthreaded plug a.

A partition 5 is. arranged transversely of the upper section, and thispartition has a central opening into which is threaded a feeding tube 6,the said tube being adapted to feed the water from the water compartmentabove the partition into the carbid compartment below the partition. Theupper end of this iced tube is normally closer by a valve 13, the stemof the valve extending upwardly through the top 3 ot the upper sectionand having a handle tor turning the same, as shown, to permit the valveto be opened and closed from outside the casing. y

n pipe 7 leads from the partition o, upwardly and outwardly through astufling box in the wall of the section 2, and then upwardly into areflector casing 9. A burner protector 8 is connected with the pipe inthe reflector casing, and this casing has the usual light transmittmgmember 9 the said member being convex in the present instance. Thestufling boX above mentioned is formed by a flange 11 on the pipe 7which engages the outer face of the casing, and a lock nut 12 which isthreaded on to the pipe and engages the inner face of the casing. Thusa. gas-tight joint is provided at this place. rlurangec. for clampingengagement between the upper and lower sections is a ring-likesupporting shelf 10 upon which is disposed a screen 10 having a centraldepressed portion llP disposed within and extending through the centralopening in the shelf and this screen has its outer edge formed with avertical flange 10 at the top of which is formed an outwardly extendinghorizontal flange 1O disposed against the u derside of the partition 5.The cup or depressec. portion 10 encircles and extends below the feedtube 6.

The lamp is arranged to be supported, whendesired, by means of a Spike15 which extends radially from a ring 16 embracing the upper section 01the casing just above its connection with the lower section, and thisring c rries also a socket 11 for a candle.

A bail 14 is connected with the cover 3 by meansof rivets 1? as shown,and a hook is connected with the bail by means of links 19 and 20. Theselinks 19 and 20 are pivoted at their outer ends to the ends of the bodyof the bail, and the links are connected by a set screw 21 which engagesa extendim longitudinally of the link nd an opening in the link 20. Thehead the set screw is rigid with the hook 18, Ad the nut thereof willclamp the two inks together on the head. The slot proides a lost motionconnection between the link 19 and the hook 18.

Referring to Fig. l, it will be noticed that the upper surface of thebody 01" the bail is grooved, and because oi the lost motion connectionthe links 19 and 20 may be folded down into the groove. The hook mayalso be folded into this groove, the said hook being bent to correspondwith the curve of the bail. The reflectorcasing 9 is connected to theupper section 2 of the casing by means of a bolt 22 and a nut 2%, the reflec'tor having a bracket plate 23 secured thereto and lapping upon thecasing, and the bolt 22 extends through the bracket plate. It will benoted that all the parts are detachable. The upper section 2 may beremoved from the lower section 1, and the feed tube 6 may be detachedfrom the partition 5. The cover 3 may be detached from the uppersection, and the reflector casing may be also detached from the uppersection. The burner 8 is separable from the pipe 7, and this pipe isseparable from both partition 5 and easing 2.

I claim:

' In a miners lamp, upper and lower casing' sections detachablyconnected, apartition extending transversely of the upper section anddefining a water compartment therein, a feed tube extending below saidpartition and communicating with said compartment, means for controllingpassage of Water through said tube, a ring-like member constitutlng ashelf clampingly engaged between said sections and spaced below saidpartition, a screen seating upon said shelf and having its outer edgeformed with a vertical flange terminating in an outwardly extendingflange engaging the underside of the partition, said screen being formedcentrally with a depressed portion constituting a cup extending throughthe opening in the shell and surrounding and extending below the feedtube, said lower casing serv- 7 ing to contain calcium carbi-cl ontowhich water from the feed tube drops, and a gas outlet p pe leading intothe lower sectlon.
